T 0 all 'whom t may concern.'

Be it known that I, Josnrrr T. WENsiLIs, a citizen of Russia, residingin the borough of Queens, county of Queens, city and State of New York,have invented an VImprovementl in Oil-Burners, of which the following isa specification.

My present invention is one Ithat relates to an apparatus for burninfuel oil for the particular purpose of heating blast furnaces, althoughobviously it is not limited to this particular use, the object of theinvention being to so construct an oil burner for thisV and similaruses'that the oil and air are ade-v quately mixed and discharged in sucha manner to the furnace or other place to be heated that the resultantcombustion is substantially complete.

In carrying out the invention, I prefer ably employ a nozzle having anoil discharge passage and fit-ted with a cap providing for asubstantially concentric air discharge passage and a device operated-bythe discharge of the air and oil for mixing and distributing the sainein such a manner, as hereinbefore stated, that the resultant combustionof the oil is as complete and perfect as possible, whereby the depositsaccumulating on the furnace or other chambers heated by oill burners iseliminated, makingthe cleaning of the furnace unnecessary, aswell asreducing the number of burners lnecessa-ryto establish and maintain apredetermined heat because of the increased efliciency of the burner byproducing substantially complete or perfect combustion. Experience hasdem'- onstrated the fact that in the use of the burner with a blastfurnace, for example, one burner made in accordance with my inventionanswers the purpose of a double/burner or two bu-rners whichwere-,heretofore employed for accomplishing the same work.

-The oilk burner made in accordance with my present invention will behereinafter more particularly described in conjunction with theaccompanying drawings in which,-

Referring to the drawing, the oil burner made in accordance with myinvention preferably comprises a nozzle member 10 made with an offsetportion 11, there being v'a lo'ngitudinal bore 12 in the nozzle memberand a similar bore 13 in the offset portion, which bores communicatewith one another at right angles, as clearly shown in Fig.y 1 of thedrawing. The nozzle member '1'0is provided with a reduced part 15, thesurface of which is screw threaded, and with a still further reduced end16. The nozzle also includes a cap 17 adapted to fit over and be turneddown to place on the screw threaded reduced portionr15- of the body ofthe nozzleVlO, and

the cap 17 is also provided with an offset portion 18 corresponding withthe offset portion 11. The borein the cap 17 is of such a diameter as toprovide an annular discharge space 19 between the same and the outersurface of the reduced end portion of the nozzle. while theoffsetportion 18 is provided` with a bore 2O communicating with the kannulardischarge passage or space 19. Within the longitudinal borel of thenozzle member, Il

employ' a rod 21. In a ypredetermined posi-" when the rod 21 is inposition in the bore of' the nozzle member, itprovides an annulardischarge passage 24 between the same and i the surface ofl the borewithin thel nozzle member and the reducedend thereof.

The apparatus hereinbefore described is preferably placed withinan elbowor other part of an air duct or pipe leading to .the

twyers in a blastvfurnace or other openin .ladies t) au Chamber reise itis .esita-f to heat by the burner. As illustrated in the drawing', thepart of the duct in which the burner is placed has an elbow 25. Theburner is secured in position in the elbow bythe pipe lines throughwhich the oil and air are supplied respectively to the annular dischargepassages 24 and 19, the former of which is indicated at 26 and passesthrough an opening provided therefor in the duct 25 and is turned downinto the end of the offset portion 11 of thev nozzle member and issecured in position by a. nut 27 or otherwise, this pipe line beingemployed to convey the oil to the burner. The other pipe line isindicated at 2S and similarly passes through an opening providedtherefor in the elbow 25 of the air duct and is turnedV down into theend of the offset portion 18 Vof the cap member 17, being secured inposition by a nut 29 or otherwise. In the pipe line 26, there is a.valve 30 to regulate and control the passage of the oil, and in the pipeline 28, there is a valve 31 to regulate and control the passage of theair. Oil passing through the pipe line 26,'as will be understood, isconveyed to t-he annular discharge passage 24, while the air flowingthrough the pipe line 2S is conveyed to the annular discharge passage 19between theA cap member 17 and the reduced end of the nozzle member.Further, as indicated, the discharge orifices of these passages, that isthe annular passage 24 and the annular passage 29, are substantiallycoincident at the right hand end of the nozzle, as viewedl in Fig. 1,and the orifice of the discharge passage 19 for the air is preferablycurved inwardly so as to direct the same into the path of the oil asdischarged from the orifice of the passage 24- and also into the ejectorand distributing device hereinafter. described. ln the form of theapparatus, as hereinbefore described, the pipe line connections are bothmade through the bottom or inside of the air duct elbow 25, but as willbe understood either one or both of these pipes may be supplied from theupper side or from either of the other sides of the elbow and for thispurpose as illustrated in Fig. 1, I have-provided the upper side of theVelbow, foreXample, with openings which, as illust-rated, are closedA bythe plugs 29.

As illustrated in the drawing, the rod 21 is made sufficiently long tobe carried through a gland'32 set in an offset por/ion 38 of the airduct elbow 25, and at this extremity of the rod, the sam-e is providedwith a square portionA 34 by means of which the sameA ma.7A be unscrewedfrom the nozzle member and by the removal of the gland, the entire rodmay be taken out of the nozzleafter the distributing device, ashereinaftery described, has also been removed for the purpose, forexample, of cleaning the bore of the nozzle or obviously for replacinganother rod should this become necessary. At the opposite end of thisrod 21 Vor that end thereof adjacent the discharge Y tor distributermember 36 is preferably conical and as indicated in Figs. 4L- and 5,.may be provided with longitudinal or straight ribs and interveninggrooves 87, 0r as indicated in Fig. 6 may be provided with series ofspiral ribs and corresponding intermediate spiral grooves 38, thislatter being the preferable form of ejector distributer. In eitherevent, the ejector distributor is maint-ained in position on the reducedend of the rod as its axis by means of a washer 39 and a lock nut 40.

In the use of the apparatus, the burner is set, for example, whenemployed with a blast furnace in substantially the position as shown inFigs. 7 and 8 of the drawing, rihe elbow of the air duct as illustratedmay be fitted with a damper i1 to control the pasof the air therethroughand-the discharge end of the air duct is placed at or adjacent theorifice of the twyer A45 in the body 42 of the blast furnace, which, asillustrated is provided with a frame A supported upon a suitable base43. Furthermore in the use of the apparatus, suitable quantities of oiland air are applied to the nozzle member and ejected therefrom, and anadditional quantityof air may be suppliedthrough the air' duct, beingdischarged from the orifice of the elbow 25 thereof and, as will now beunderstood, in the use of the apparatus the oil and air being dischargedfrom the orilices of the annular passages in the nozzle cause theejector distributer to revolve, which, in so doing, not only mixes theair and oil thoroughly, but distributes and ejects the same in suoli a;manner that combustion of the oil is practically complete.
